for the palladium-catalyzed Suzuki-Miyaura and carbonyl enolate coupling of unactivated aryl arenesulfonates was developed utilizing XPhos, 1, and Pd(OAc)2. This is of significant interest because aryl tosylates and aryl benzenesulfonates are more easily handled and considerably less expensive than aryl triflates. This catalyst system effects the coupling of a variety of aryl, heteroaryl, and extremely
Dicyanovinyl-substituted J147 analogue inhibits oligomerization and fibrillation of β-amyloid peptides and protects neuronal cells from β-amyloid-induced cytotoxicity

In this study, the direct Nickel-catalyzed Suzuki–Miyaura coupling reaction of phenols and arylboronicacids via C–O bond activation using 2,4,6-trichloro-1,3,5-triazine (TCT) is described. Initially, phenols were reacted with TCT to give the corresponding 2,4,6-triaryloxy-1,3,5-triazine (TAT) products. Subsequently, arylboronicacid, base and Ni-catalyst were added to the generated aryl C–O electrophile
